underneath it. How can I do that and size the crescendo and decresendo to my liking (say span the < to last 3 quarters of the whole note and the > to last a quarter)

I have a very handy music function for that (based on an idea by David K.):

after =
#(define-music-function (t e m) (ly:duration? ly:music? ly:music?)
   #{
     <<
       #m
       { \skip $t <> -\tweak extra-spacing-width #empty-interval $e }
     >>
   #})

With that you can write things like:
\new Voice {
  \after 2. \> dis1\< <>\! |
  \after 4 \< \after 2 \> \after 2. \p dis1
  \after 2. \stopTrillSpan dis1\startTrillSpan
  \after 2 \upbow dis1\downBow
}

Note that it’s essential to explicitly create the voice with \new Voice, else the <<>> in the music function will create new voices and it won’t work.
